Integrating target capture with whole genome sequencing of recent and natural history collections to explain the phylogeography of wild‐growing and cultivated cannabis

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Cannabis has been used by humans for millennia, resulting in diverse landraces and uses. Its complex legal status and economic importance make sampling wild‐growing populations difficult, limiting past studies to modern cultivars with low genetic diversity. Our research provides crucial insights into the genetic diversity of wild‐growing and cultivated

Comprehensive tree assessments for prioritising conservation action in Mesoamerica

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Tree species are of ecological and social importance globally. Mesoamerica has a diverse tree flora, and the region has experienced major changes in natural habitats due to human activities. In this study, for the first time, we assessed the conservation status of the region's tree species and found that 46% of trees in the region are at risk of ...

The women honoured in flowering plant genera: From myth to reality

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Many flowering plant genera are named for people, but there is a gender gap in this naming, with only 6% of eponyms honouring women. Here we explore this gap by examining in detail women for whom plant genera are named. Our open shared dataset serves to make women honoured in plant genera more discoverable, resulting in further impact by allowing ...
